Verbena plant named sunvivaro

ABSTRACT

Disclosed herein is a Verbena plant which has erect growth habit and good plant height. The plant has plentiful flowers in a spike, and great profusion of blooms. The blooming period is late April to November and flowering duration is long. The whole bush remains in bloom for a considerable period of time. The flower size is large and the petal color of the flowers is vivid purplish red without eye. The plant is highly tolerant to heat, and has high resistances to pests and diseases, particularly powdery mildew, and high resistance to rain.

BACKGROUND OF THE VARIETY

[0001] The present invention relates to a new and distinct variety of verbena plant obtained from crossing a wild type of verbena plant Verbena peruviana (♀) native to Brazil and another wild type of verbena plant Verbena peruviana (♂) native to Brazil.

[0002] Verbena is a very popular plant and is used for flower bedding and potting in the summer season. There are only a few varieties of Verbena plants which is much branching, many flowers in a spike, a long flowering duration and which have a high resistance to rain, heat, cold, and disease. Accordingly, this invention was aimed at obtaining a new variety having a erect growth habit, strong branching, many flowers in a spike, long flowering duration, high tolerance to heat and cold, and resistances to diseases and pests, and also having a vivid purplish red color petal.

[0003] The new variety of Verbena plant according to this invention originated from crossing of a wild type of verbena plant Verbena peruviana (♀) native to Brazil and another wild type of verbena plant Verbena peruviana (♂) native to Brazil.

[0004] First of all, 32 seedling were obtained in the autumn of 1993, from crossing a wild type of verbena plant VBA (Verbena peruviana f. rosea) as female parent and another wild type of verbena plant VBB (Verbena peruviana f. rosea) as pollen parent in the spring of 1993. From this crossing, one seedling was selected in view of erect growth habit, branching and petal color, and propagated by cutting, and then grown as a trial by flower bedding and planter from the spring of 1994. Finally a trial by flower potting and bedding was carried out on the selected one plant to the autumn of 1995. The botanically characteristics of the selected one seedling was examined, using similar varieties ‘Sunvivapa’ (Appl. No.8239 under the Seeds and Seedlings Law of Japan) and ‘Showtime blaze’ for comparison. As a result, it was concluded that this Verbena is distinguishable from any other variety whose existence is known to us, and is uniform and stable in its characteristics. This new variety of Verbena plant was named ‘Sunvivaro’.

[0005] In the following description, the color-coding is in accordance with The Horticultural Color Chart of The Royal Horticultural Society, London, England (R.H.S. Color Chart), and the Inter-Society Color CouncilNational Bureau of Standards Color Name (I.S.C.C.-N.B.S. Color Name). A color chart based on The Japan Color Standard for Horticultural Plant (J.H.S. Color Chart) is also added for reference.

[0006] The female parent VBA and the pollen parent VBB, used in the obtaining of this new variety ‘Sunvivaro’, was a wild type of verbena native to South Brazil and Verbena peruviana. This wild type of verbena plant is presently maintained at the Hakushu Nursery Center of SUNTORY Ltd., residing at 2913-1 Torihara, Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan.
